I'm still skeptical about laser projectors -- while the technology is impressive, the practicality is still a little limited. And unfortunately, Microvision's demo of their SHOWWX projector here at Macworld 2010 didn't do much to change my mind. It's a nice little device -- it's almost exactly the size of the iPhone, and the rep told me that most of the unit is actually the battery -- and there are some good applications for it. But for the consumer market that Microvision really wants, the $500 unit (that will go on sale in March) is still a little too small in terms of scale and usability.
Just using the device, which will project clear images and video from an iPhone or iPod on a wall about three to four feet away (more or less depending on ambient light), you can tell that the idea of a microprojector is almost at the level where it could be really successful. As the rep said to us, the iPhone is a 1:1 device, and while many of us do use it to show pictures and video to each other, it's really only meant to show one person at a time. But the projector goes to a "1 to few" relationship instead, and that's a prospect that will be appealing to anyone who wants to show off business presentations, video, or pictures of family members to anyone else.
